Mistake
In this family, everyone is telling lies.
Pete never wanted another child. Before baby Erin was born, they were happy. If Natalie hadn't got pregnant, he would never have done what he did.
Natalie knows things have been difficult since the surprise arrival of Erin. Life with Pete and their two other children - Emily and Zadie - has been balancing on a knife-edge.
Now their home is full of guests at a party Natalie didn't want to throw - and she's about to reach breaking point.
But so is her family.
Because everyone has a secret that they've been hiding and when Erin suddenly disappears everyone becomes a suspect.
Surely no one here would want to harm their baby? But after the events of the party there are plenty of people who would want to hurt Natalie.
Including her husband...
